Home Study Course in Food Protection
The main purpose of our home study course is to provide an introduction to food safety. It is well known that applying
food safety principles will reduce the risk of foodborne illness.
There are four sections in this booklet:
Section 1—Food Safety in Alberta
Section 2—Foodborne Illness
Section 3—The Causes of Foodborne Illness
Section 4—How to Prevent Foodborne Illness
The home study course can be done on your own time. This course can be taken by anyone who
prepares food including people working in food businesses, daycares, long term care facilities,
volunteers, and those who cook at home. Read through each section of this booklet and do the
review questions.
The exam is optional. The exam has a total of 25 multiple-choice and true or false questions. The
passing mark is 80%. Upon successful completion of the exam, you will be awarded a Home Study
Course Certificate, which is valid for three years.
Please note that this course does not meet provincial certification requirements.
Thank you for your participation and the interest you have shown in our home study course.

FOOD INSPECTIONS
Section 1. Food Safety in Alberta
The Alberta Health Services (AHS) food inspection program is carried out by certified Public Health
Inspectors (PHIs) / Environmental Health Officers (EHOs) who work for Environmental Public Health.
All public food facilities, from hot dog carts, grocery stores, to full service restaurants are inspected.
A Health Inspectors’ authority lies within the Alberta Public Health Act. During food inspections,
Health Inspectors ensure that operators are following government legislation such as the Alberta
Food Regulation. The Food Regulation requires that a food establishment must hold a valid food
handling permit issued by AHS. To make an application for a food handling permit, visit the website
www.albertahealthservices.ca/eph.asp or contact your local Health Inspector.
There are a few exceptions to the requirement for a food handling permit. Special events, temporary
food establishment and community organization functions do not require a food handling permit,
although they do require approval from AHS and must follow regulatory requirements to ensure food
is handled in a safe manner.
The Public Health Act and the Food Regulation are available online at the Alberta Queen’s Printer
website at www.qp.gov.ab.ca or by telephone at (780) 427-4952.
Restaurant inspections can be viewed at www.albertahealthservices.ca/eph.asp . Court cases and
food establishment closures can also be viewed at this site.
FOOD SAFETY EDUCATION
The Alberta Food Regulation states that food operators are responsible for completing the
appropriate food safety training. There is a requirement for one person per shift to have provincially
recognized food safety certification if there are six or more food handlers on site. Food handlers
include cooks, servers and bartenders. If there are less than six food handlers on site, one person
in care and control of the establishment must have certification. This person should be on site most
of the time. Information on provincial certification in food sanitation and hygiene can be found at
www.albertahealthservices.ca/eph.asp.
The home study course is a short 2–3 hour (mini) course and does not provide provincial
certification.

Section 2. Foodborne Illness
Each year an estimated 11 – 13 million Canadians are ill from foodborne illness. Many people do
not report foodborne illness to the health department or their doctor.
Foodborne illness, commonly called food poisoning, is caused by consuming food or beverages
contaminated with bacteria, the toxins or poison that some bacteria produce, viruses, parasites, or
moulds. These are called pathogens or harmful microbes.
Anyone can become ill with foodborne illness. However, some people are at a higher risk for food-
borne illness. These include:
babies or very young children
seniors
pregnant women
sick people
people with little resistance to illness; for example
cancer, transplant and AIDS patients
Common symptoms of foodborne illness:
diarrhea
vomiting
nausea
stomach cramps
headache
fever
Symptoms can last for several hours, days or months. Foodborne illness can cause mild illness or
very serious illness. People may have to stay off work. Sometimes people have to go to the
hospital. Foodborne illness can even cause death.
A Listeria outbreak in 2008
caused 23 deaths in Canada.
The outbreak was
linked to ready-to-eat deli
meat products contaminated
at a Canadian food plant.
Listeriosis is a rare but serious
foodborne illness and
can result in death. Pregnant
women, the elderly and
people with weakened immune
systems are at the
greatest risk of becoming ill.
Information on Listeria and
other foodborne illnesses
can be found at:

FACTS
Food that contains harmful microbes (germs) or their toxins (poison) may look, taste, and smell
normal.
In many cases, foodborne illness is not caused by the last meal or food eaten. It can take time
for symptoms to develop. With E. coli O157:H7 infection (a type of foodborne illness), it can take
2-10 days for the signs of illness to appear. It can take 6-72 hours for the symptoms of
Salmonella infection to appear.
It takes only a small number of microbes to cause some types of foodborne illness. Two
examples are Shigella infection and E.coli O157:H7 infection.
The harmful microbes that cause foodborne illness can also be spread by contact with another
person, touching an animal, and swimming or wading in recreational pools.
When two or more people have symptoms of foodborne illness after eating the same food or at
the same facility, it is called an outbreak. Some outbreaks are small. Others are very large. In
1996, a Salmonella outbreak in Calgary, Alberta caused illness in more than 100 people.
Foodborne illness is very expensive for health services, the foodservice industry, and society.
Each year in Canada, $12–15 billion dollars are spent on foodborne illness.
For more information on foodborne illness, go to the Foodborne Illness Chart on page 34.

MICROBES
Section 3. The Causes of Foodborne Illness
Microbes are very small organisms that live all around us, but we cannot see them. (Micro means
very small.) They are on plants, animals and people and in the air, soil, and water. Microbes are
sometimes called germs.
Most microbes do not harm us. Some microbes are good for us, such as the bacteria used to make
yogurt. Only a small number of microbes cause foodborne illness. These are called disease
causing or pathogenic microbes.
The presence of some harmful microbes is enough to cause foodborne illness. Other harmful
microbes need time and the right conditions to increase in number or produce toxins (poison) before
they cause illness.
Parasites, moulds, viruses and bacteria are examples of microbes that can cause foodborne illness.
Parasites
Parasites are microbes that live in, or on, other organisms. Parasites do not grow in food. They are
destroyed by heating and freezing.
Some parasites are too small to be seen, such as Giardia and Cryptosporidium. They can cause
waterborne illness when someone drinks untreated water. Make sure that water is safe to drink
when you are camping or hiking outdoors. You may have to boil it first to make it safe to drink.
Other parasites are worms that you can see, such as roundworms and tapeworms.
How to control parasites:
Wash your hands after using the toilet and before preparing food.
Cook food to safe temperatures.
Use safe water supplies.
Wash all fruit, vegetables and salad greens.
8

Moulds
Moulds cause food to spoil. Some moulds can also produce toxins (poison). Some good moulds
are used to ripen certain cheeses.
Moulds can grow on acidic food like oranges and tomatoes. They also grow in food with a lot of
sugar, such as jam. They like warm, moist conditions and a good supply of air.
How to control moulds:
Store food at the proper temperatures and in a dry area.
Use food quickly. Check best before dates.
Check food carefully for mould. If you see any mould, the safest thing to do is throw it out.
Clean and sanitize utensils, containers and any surfaces that touched mouldy food.
Viruses
Viruses are the smallest of all the microbes. Viruses do not grow in food. They can only grow in a
living cell.
Viruses can be spread through contaminated food and water, by a person handling food, or from
one person to another. Norovirus and Hepatitis A are two viruses that cause foodborne illness.
How to control viruses:
Wash your hands after using the toilet and before preparing food.
Wash all fruit, vegetables and salad greens.
Use safe water supplies.
Cook food to safe temperatures.
9

Bacteria
Bacteria are found everywhere in our environment. Although most bacteria are harmless or even
beneficial, some are harmful and can cause foodborne illness. Harmful bacteria are called
pathogens. These pathogens are commonly found in human and animal waste, in soil, and on raw
meat, poultry and fish.
Examples of foodborne illness bacteria:
Campylobacter
Clostridium botulinum (Botulism)
Clostridium perfringens
E. coli O157:H7
Listeria monocytogenes
Salmonella
Shigella
Staphylococcus aureus (Staph)
Bacteria need certain things to grow: (FAT TOM)
Food
Food
Acidity (pH is a measurement of acidity or alkalinity)
Temperature
Time
Oxygen (Air)
Moisture (Water)
Harmful bacteria grow very well in food that is rich in proteins, vitamins and minerals. Meat, poultry,
fish, eggs, dairy products, cooked vegetables and cooked grains are great sources of food for
bacteria. These foods are called “potentially hazardous” because bacteria can grow on them. If
these foods are not safely stored and prepared, they could cause foodborne illness.
Harmful bacteria have also been found on salad greens and fruit.
10

Acidity (pH)
This is the amount of acidity or alkalinity in a food. Lemons, limes and vinegar are examples of
highly acidic foods. Highly acidic foods stop bacteria from growing, but do not kill them. Bacteria
prefer foods that are only slightly acidic, such as meat, poultry and fish.
Temperature and Time
Bacteria need the right temperature to grow. When conditions are right, bacteria can multiply every
fifteen to twenty minutes. Most foodborne illness bacteria like temperatures between 4°C and 60°C
(40°F to140°F). This range of temperatures is called the “Danger Zone”. The longer food is in the
Danger Zone, the larger the number of bacteria that can grow.
If the temperature is at 4°C (40°F) or colder, bacteria can survive but may grow slowly. If the
temperature is too hot, at 60°C (140°F) or hotter, bacteria will stop growing. The Alberta Food
Regulation requires specific temperatures for storing, cooling, freezing, heating and hot holding
potentially hazardous food.
Oxygen (Air)
Bacteria need the right kind of air to live. Most bacteria grow only if they have oxygen. Other
bacteria can only grow if there is no oxygen, for example Clostridium botulinum, the bacteria that
causes botulism.
Moisture (Water)
Bacteria need water. The foods associated with foodborne illness, such as meat, fish, poultry, eggs,
dairy products, fruit, vegetables and salad greens, have a lot of water in them.
How to control bacteria:
Keep potentially hazardous food out of the Danger Zone.
Keep food cold, at 4°C (40°F) or colder.
Keep food hot, at 60°C (140°F) or hotter.
Cook food to safe temperatures.
Chill hot food quickly.
Wash your hands.
Clean and sanitize utensils, equipment and food preparation surfaces.
11

HOW FOODBORNE ILLNESS MICROBES ARE SPREAD
Foodborne illness microbes come from many sources: animals, people, soil, water, food, air,
equipment, utensils and other objects.
Animals
Animals can be a source of harmful microbes. Raw meat, poultry and fish can be a source of
bacteria such as Salmonella, Campylobacter and E. coli O157:H7. Everyone needs to wash their
hands, and wash and sanitize kitchen surfaces and utensils after handling raw meat, poultry and
fish.
Insects and mice can carry bacteria and viruses on their bodies. If you have insects or mice in
your food facility, you need to call a licensed pest control operator.
People
Soil
Water
People can carry harmful microbes in their intestinal tract, such as Salmonella and E. coli
bacteria. If hands are not washed well after using the toilet, these microbes can be spread to
anything the person touches, such as food, another person or a surface. This way of spreading
microbes is called the “fecal–oral route”.
Foodservice staff who handle raw meat, poultry and fish can spread harmful microbes to other
food. Wash your hands before you touch other food in the kitchen.
People may have bacteria called Staphylococcus aureus on their skin and in their nose and
throat. This bacteria can be spread to food by coughing or sneezing, or by touching food if you
have infected cuts or sores on your hands. This bacteria can also be spread to food if you blow
your nose and then touch food without washing your hands.
Harmful microbes may be found in soil. Vegetables and fruit that grow in soil may have harmful
microbes on their outer surfaces. Salmonella and E. coli bacteria have been found on the outside
of cantaloupes and tomatoes.
Untreated water from lakes, streams and rivers can be a source of harmful microbes. Some
examples are E.coli O157:H7, and parasites such as Cryptosporidium and Giardia. Water used
in food service must be safe to drink.
12

CHEMICALS
Chemical food poisoning can result from eating naturally poisonous foods. For example, certain
types of mushrooms (such as the Amanita species) may contain natural poisons. Chemical food
poisoning may also be caused if food is contaminated with chemicals.
Some California high school students became ill very quickly after drinking punch. Their
symptoms included nausea, vomiting, cramps, dizziness and headache. The diagnosis: zinc
poisoning. The punch was made and stored in a galvanized metal container with a corroded
interior. The container was not intended for food.
How to prevent chemical food poisoning:
Buy your food from licensed suppliers.
Wash fruit, vegetables and salad greens.
Use approved food-safe cookware and equipment.
Use safe amounts of food additives such as MSG (monosodium glutamate).
Do not store chemicals in food containers and do not store food in chemical containers.
Label all chemicals.
Use chemicals safely. Read the labels.
Store chemicals away from food.
Allergic Reactions to Food
Eating certain foods or ingredients can cause allergic reactions in a small number of people.
These reactions can be minor or life-threatening.
The following foods account for 90% of all food-related reactions:
milk and dairy products
eggs
wheat
soy
peanuts
tree nuts (examples are almonds, brazil nuts and cashews)
shellfish and fish
13

Reduce the risk of allergic reactions:
Have a plan for medical emergencies.
Make sure all staff know the ingredients that are used in the facility. Someone with a peanut
allergy may ask if the facility uses peanut oil. If staff or management don’t know the answer, tell
the customer. The customer can then make other choices.
Prevent cross contamination. Tiny bits of food left on hands, a knife, spoon, cutting board or
dishcloth can spread to other food and cause allergic reactions.

Section 4. How to Prevent Foodborne Illness
THE TOP 5 FOOD HANDLING MISTAKES THAT CAUSE FOODBORNE ILLNESS*
1. Ill Food Handlers
Many foodborne illnesses are caused by ill food establishment employees. People with symptoms
of nausea, vomiting and/or diarrhea should not handle or prepare food for others. Food
establishment employees often return to work too soon after being ill or they return to work while
still suffering from symptoms.
2. Temperature Abuse
Potentially hazardous foods that are stored in the temperature Danger Zone (between 4°C and
60°C) allow bacteria to grow rapidly. Do not keep potentially hazardous foods in the temperature
Danger Zone for longer than 2 hours. Keep hot foods hot and cold foods cold.
3. Inadequate Cooking
Foodborne illnesses are caused when raw foods, such as meat, poultry and fish, are not thoroughly
cooked. Often a thermometer is not used to check the internal temperature of the cooked food.
Foodborne illness can also occur when leftover foods are not reheated to an internal temperature of
at least 74°C.
4. Cross Contamination
Cross contamination is a major cause of foodborne illness. It can occur when dirty equipment or
utensils are used to handle or prepare food. Cross contamination can also happen when the same
cutting board that is used to prepare raw meat is used to prepare cooked or ready-to-eat foods; raw
meats are stored too close to or above ready-to-eat foods; and, hands are not washed properly
after handling raw meats and poultry.
5. Improper Cooling of Cooked Food
When hot foods take too long to cool, bacteria can grow rapidly. Hot foods are often left to cool in
large stock pots or deep containers instead of shallow, metal containers. Rapid cooling techniques
can prevent foodborne illnesses from occurring. Rapid cooling techniques include using an ice bath,
an ice wand, stirring frequently or using shallow metal containers.
*Based on Alberta Health Services, Edmonton Zone statistics, 2007
16

To Prevent Foodborne Illness, Follow Two Key Principles When Handling Food:
1. Keep food out of Danger Zone temperatures.
2. Protect food from cross contamination.
Practical ways to do this are given under the Eight Steps to Safe Food
THE EIGHT STEPS TO SAFE FOOD
Step 1 — Buying and Receiving Food
Buy from approved suppliers.
Make sure food is delivered at safe temperatures.
Check new food supplies for: best before dates, expiry dates, signs of spoilage, damage and
insects.
To review current food recalls and allergy alerts or to sign up for free, automatic email notices on
food recalls and allergy alerts, go to the following link:
Canadian Food Inspection Agency, Food Recalls and Allergy Alerts, http://www.inspection.gc.ca/
english/corpaffr/recarapp/recaltoce.shtml
Step 2 — Storing Food
Put fresh and frozen foods in refrigerators, coolers and freezers as soon as they are delivered.
Follow the FIFO rule (First In, First Out). Use food supplies in the order they were received.
Keep refrigerators and coolers at 4°C (40°F) or colder. Keep freezers at –18°C (O°F) or colder.
A thermometer needs to be in each fridge and freezer to measure the temperature.
Maintain good air circulation in refrigerators, coolers and freezers. Do not overfill with food.
Store raw meat, poultry and fish below cooked or ready-to-eat foods such as salads,
sandwiches and cakes.
Do not store food on the floor of walk-in coolers or dry storage areas.
17

Step 3 — Preparing Food
Wash your hands before preparing food.
Start with clean and sanitized utensils, cutting boards, equipment and work surfaces.
Wash fruits, vegetables and salad greens with cool, running water to remove dirt, insects,
harmful microbes and pesticides.
Leafy products like lettuce, spinach, parsley and cilantro may need several rinses in clean
water. Salad mixes have a short shelf-life. Check the “Best Before Date” and use them up
quickly.
For more information on washing fruits and vegetables, go to the following link: Canadian Food
Inspection Agency, Food safety facts for fresh fruits and vegetables, http://
www.inspection.gc.ca/english/fssa/concen/specif/fruvege.shtml
Thaw frozen food safely:
In the refrigerator or walk-in-cooler. Place the frozen food on a tray or plate and put it on the
bottom shelf.
In cold running water. Use large sinks. Clean and sanitize the sink after the food is thawed.
In a microwave oven, and cook immediately after food is thawed.
Thawing at room temperature is not safe.
Food Preparation and the Danger Zone
Work quickly with food so that it spends only a short amount of time in the Danger
Zone, 4°C (40°F) – 60°C (140°F).
Put the food in the cooler or cook it and serve immediately.
Do not store or display food in the Danger Zone.
Follow the two hour rule: The total time that food is in the Danger Zone, from receiving
to service, should never be more than 2 hours. Otherwise, it must be thrown away.
18

Food Preparation and Cross Contamination
Cross contamination is the spread of bacteria, viruses or parasites from one food to another, by
hands, utensils or equipment. Direct contamination occurs if raw food touches cooked or ready to
eat food or if a food handler sneezes or coughs into food. To avoid cross contamination:
Wash your hands when you come into the kitchen and after handling raw meat, poultry and fish.
Keep raw meat, poultry and fish away from cooked food or ready-to-eat food.
Use separate knives, tongs, spoons, ladles and scoops for raw and cooked or ready-to-eat food.
Use separate cutting boards for raw and cooked or ready-to-eat food.
Use a clean spoon each time you taste food. Do not stick your fingers in food.
Clean and sanitize all equipment, utensils and surfaces that touch food.
Change aprons and uniforms that are soiled with blood from raw meat and poultry.
Change dish cloths and wiping cloths often. When not in use, store cloths in a sanitizing solu-
tion. Change the solution after the breakfast rush, the lunch rush and the dinner rush. Change
the solution if it is dirty or soiled. (See page 25 for directions on making sanitizing solutions)
Here is an example of cross contamination. In 1998, more than 150 customers became ill
after eating at a Minnesota restaurant. Kitchen staff prepared raw chicken and then pre-
pared the lettuce for 200 salads, without washing their hands.
The outbreak was caused by Campylobacter bacteria. These bacteria can be found on
raw or undercooked chicken.
Step 4 — Cooking Food
Cook or heat food to safe temperatures. Cooking
food to temperatures of 74°C (165°F) will kill most
bacteria.
Measure the temperature of cooked food with a
thermometer. Clean and sanitize the stem of the
thermometer before each use.
Cleaning a food thermometer with an alcohol wipe
19

Step 5 — Cooling Food
Cool food quickly to 4°C (40°F) or colder to reduce the risk of foodborne illness. Food should
cool from 60°C (140°F) to 20°C (70°F) or less within 2 hours and from 20°C (70°F) to 4°C (40°
F) or less within 4 hours.
It is not safe to leave hot food at room temperature to cool, or to put large amounts of hot food
in the cooler. In both cases, the food does not cool quickly enough and stays in the Danger
Zone for a long time.
Salads, sandwiches and desserts also need to be cooled quickly to 4° C (40°F) or colder.
Three ways to cool food quickly:
1. Fill a large sink with lots of ice. Add cold water. Place pots or containers of hot food in the ice
water bath. Stir often. Add ice as necessary. Tip: Use ice wands to stir containers of hot food.
2. Put large amounts of food into smaller containers or shallow pans no more than 10 cm (4 in)
deep, and place in the cooler. Do not cover the containers until the food has cooled. Use
metal containers or pans instead of plastic, if possible.
3. Cut large pieces of meat or poultry into smaller pieces. Put in shallow pans and refrigerate.
Cover when cooled.
Step 6 — Hot and Cold Holding of Food
Food served at buffets or salad bars needs to be handled safely.
Hot holding units such as steam tables must keep food at 60°C (140°F) or hotter.
Cold holding units must keep food at 4°C (40°F) or colder. If ice is used to cool foods, the ice
must come up the sides of the containers to the level of the food.
Measure the temperature of food every hour to make sure it is not in the Danger Zone.
Do not add fresh portions of food to old food.
Use sneeze guards (plastic shields) or covers to protect food on buffets and salad bars.
Have tongs or serving spoons for each food container.
20

Step 7 — Reheating Food
Reheat leftover food quickly to 74°C (165°F) or higher within 2 hours. This includes food made
in advance for banquets and catered meals.
Bring soups, stews, gravies and stock to a boil. Stir often.
Do not reheat food more than once.
Hot holding equipment should not be used to reheat food. Food should already be hot when
placed in hot holding equipment
Step 8 — Serving Food
Setting the table:
Pick up cutlery by the handles.
Do not touch the rim of glasses or cups.
Throw out chipped or cracked glassware and dishes.
Serving food safely:
Do not touch food or drinks with your fingers.
Use tongs or a scoop to pick up ice. Do not use your hands or a glass.
Throw away food that falls on the floor.
Wash and sanitize cutlery that falls on the floor.
Keep serving stations clean.
Prevent cross contamination.
Clean and sanitize.
Follow good personal hygiene standards.
Clearing tables:
Throw away food left on a customer’s table such as open food like bread.
Wash and sanitize tables.
Wash your hands after touching dirty dishes and cutlery.
21

Single service dishes and cutlery:
Use disposable (single service) cutlery and dishes only once.
Store single service cutlery with the handles up, or facing the same way. Customers can then
pick up the cutlery by the handles.

CLEANING AND SANITIZING
Cleaning removes food and grease from utensils, dishes, food preparation surfaces and
equipment. Wash with hot water and soap and then rinse. Sanitizing reduces the number of
harmful microbes to a safe level. Sanitizing is done with chemicals or hot water. There are 3
chemical sanitizers approved for use in Alberta:
Chlorine or sodium hypochlorite (bleach is an example): 100 parts per million or ppm. To
make a 100 ppm chlorine sanitizing solution, add 15 ml (1 tablespoon) of bleach (5.25% chlo-
rine) per 4.5 litres (gallon) of water. For a smaller batch, use ½ teaspoon of bleach per liter of
water. Mixed bleach solutions are unstable. A fresh solution needs to be made at least daily.
―Quats‖ (quaternary ammonium compounds): 200 ppm. Mix according to the manufacturer’s
recommendations.
Iodine (iodophor compounds): 12.5 – 25 ppm. Mix according to the manufacturer’s recommen-
dations.
The strength or concentration of a chemical sanitizer is meas-
ured in parts per million or ppm. If you sanitize with chemicals,
you need to test the strength of the sanitizer with test strips.
If hot water is used for sanitizing, measure the temperature of
the water. It should be over 77°C (170°F). This temperature can
only be maintained if there is a booster heater in the third
compartment.
Sanitizing requires three things:
a clean and rinsed surface
the correct strength of sanitizer or the correct water temperature
Test strips
the correct contact time of the sanitizer on a surface (at least two minutes)
24

Dishwashing
In foodservice, dishwashing is done manually or by machine. Dishwashing has 4 steps: wash,
rinse sanitize and air dry.
1. Manual Dishwashing
A. Scrape and rinse the dishes. Soak
cutlery in detergent and warm water.
B. Sink #1 Wash: Fill the sink with
hot water (45°C/113°F). Add
detergent.
C. Sink #2 Rinse: Fill the sink with
hot water (45°C/113°F). Rinse the
dishes to remove soap and food
scraps.
D. Sink #3 Sanitize: Use chemicals or hot water. Soak for 2 minutes.
E. Air dry.
Chemicals
Fill the third sink with hot water (45°C/113°F).
Add chlorine (100 ppm), quats (200 ppm) or iodine (12.5– 25 ppm). Note: 15 ml or 1
tablespoon of bleach (5.25% chlorine) added to 4.5 litres (1 gallon) of water approximately
gives a concentration of 100 ppm of chlorine.
Check the concentration of the sanitizer with a test strip for that chemical. Instructions are on
the paper label. Chlorine test strips should be dipped in the solution and immediately
compared with the colour chart for 100 ppm.
Soak the dishes for two minutes in the sanitizer, then air dry on a drain rack. Do not dry with a
cloth towel.
25

Hot Water
Fill the sink with hot water over 77°C (170°F). You will need a special water heater, baskets to
hold the hot dishes and a thermometer to check the water temperature.
Let the dishes soak for two minutes, then air dry.
2. Machine Dishwashing (also called Mechanical Dishwashing)
The temperature of the wash and rinse water depends on the type of sanitizer used.
See the chart below.
Type of Dishwasher
Cutting Boards
Clean and sanitize cutting boards and chopping blocks after each use.
Wash with warm, soapy water. Rinse.
Apply a 100 ppm solution of chlorine or 200 ppm solution of quats.
Air dry.
Both finished hardwood and plastic boards are acceptable if they are in good condition. Throw
away cracked boards or boards with deep grooves. Plastic boards can be washed in the
dishwasher.

PERSONAL HYGIENE
Personal hygiene is very important. It helps stop the spread of harmful microbes and protects
food, customers and staff. Here are two key guidelines:
1. Work only when you are well
Do not work in food service if you have symptoms such as diarrhea or vomiting, a cold or a sore
throat. You are at higher risk of spreading foodborne illness. Alberta Health Services may require
that you stay off work if you have a confirmed foodborne illness such as Salmonella or E. coli
O157:H7.
The fecal-oral route is a common way of transferring pathogens to food. This occurs when a food
handler does not wash their hands properly after using the toilet and then handles food or objects
which then enter another person’s mouth.
2. Wash your hands
Your kitchen needs to have at least one handwashing sink with soap and paper towels.
Wash your hands:
at the beginning of a shift
whenever you come back into the kitchen
before preparing food
after touching raw meats, poultry and fish
after touching dirty utensils or equipment
after using the toilet
before and after eating
after touching garbage
after smoking
after blowing your nose, coughing or sneezing into your hands
after touching money
30

How to Wash Your Hands:
1. Wet your hands.
2. Put soap on your hands.
3. Rub your hands together for at least 20 seconds. Wash your wrists too.
4. Use a nail brush to scrub under your nails, the back of your hands and between your fingers.
5. Rinse your hands with warm water.
6. Dry your hands with a paper towel.
Gloves in Foodservice
Gloves do not replace hand washing.
Gloves can become contaminated, just like hands.
Start with new disposable gloves with each new task.
Wash and dry your hands before you put on gloves.
Wash your hands after you remove your gloves.
Throw your disposable gloves away after each use.
Hand Sanitizers
Key points about alcohol-based hand sanitizers:
1. Hand sanitizers do not replace washing with soap and warm water. Note: Alcohol-based hand
sanitizers can be used as an extra step after handwashing.
2. Hand sanitizers must have an alcohol content of at least 63%.
3. Hand sanitizers work best on visibly clean hands. Grease, food particles or dirt will reduce the
effectiveness of the sanitizer.
4. Add the product to the palm of one hand, dip all of your fingertips into the sanitizer and rub your
hands together to distribute the sanitizer. Hand sanitizer should cover all parts of your hands
and fingers. Keep rubbing your hands until they are dry, about 15–30 seconds. Do not rinse off
the sanitizer.
